In flexCausal: Causal Effect Estimation via Doubly Robust One-Step Estimators and TMLE in Graphical Models with Unmeasured Variables

Get the descendants of a node OR nodes in a graph.

Description

Function to extract the descendants of a node OR nodes in a graph object. Descendants of a node Vi are set Vj such that there is a directed path Vi->...->Vj. Descendants set including Vi itself by convention.

Usage

f.descendants(graph, nodes)

Arguments

graph	A graph object generated by the make.graph() function.
nodes	A character vector of nodes for which to extract children.

Value

A vector of vertices contains descendants set of the given nodes.

Examples

graph <- make.graph(vertices=c('A','M','L','Y','X'),
bi_edges=list(c('A','Y')),
di_edges=list(c('X','A'), c('X','M'), c('X','L'),
c('X','Y'), c('M','Y'), c('A','M'), c('A','L'), c('M','L'), c('L','Y')))
f.descendants(graph, c('A'))
